Random Sleep on Macbook Air


New member
replaced the logicboard in a macbook air; works fine except it randomly goes to sleep while typing on multiple occassions. Any idea what could cause this?


11" or 13". In any case SMC_LID is being pulled down due to corrosion somewhere. Look at diagram where SMC_LID all ends up and inspect for corrosion. Common is IO board/cable and trackpad/connector/cable. On 11" the lid sensor is on the board between the ports on the left sides.
